Elevator of the present invention by hoist cable (the 1st rope) with cage and balance block suspended load, described hoist cable volume is hung to hang and is held in hoist cable with on (the 1st) direction inversion belt wheel, and the lifting of cage drives and lifting by driving rope (the 2nd rope) with cage or balance block bonded assembly; Described driving rope is driven with traction wheel by the driving that is arranged on elevating road one side, limits with the lifting of the brake equipment on the direction conversion belt pulley to cage by being arranged on described hoist cable.Promptly, because the hoist cable of cage is separated with the driving rope, on the belt pulley of hoist cable side, brake equipment is set, can alleviate driving the certainty and the reliability burden of rope, the specification that relaxes rope maybe can reduce the radical that drives rope, consequently make simplifying the structure of the machine class that drives the rope side, can realize miniaturization, particularly have can realize in the elevator unmatchful in the effect of the many Machine Rooms of the installing space restriction of lift facility.
Example 1
Fig. 1 is embodiments of the invention 1, represents the concept map of the structure of lift appliance of the present invention; Fig. 2 for see from the A-A section of Fig. 1, the expression hoist cable is with the part figure of direction conversion belt pulley.
Among the figure, the 1st, be provided with the elevating road of lift appliance, the 2nd, the cage that is equipped with the passenger, in elevating road 1, carries out lifting, the 6th, hang the hoist cable of holding cage 2 by an end, the 3rd, hang the balance block that is held on hoist cable 5 other ends, 8 hoist cables that are arranged on the bearing of trend of elevating road top, conversion hoist cable 6 are changed belt pulley with direction.On the other hand, the 7th, an end and balance block 3 bonded assemblys are driven rope, extend upward and roll up to hang over and drive rope and drive with after on the traction wheel 10, driving rope extends downwards and roll up and hang over the driving rope that is arranged at elevating road 1 bottom and change on the belt pulley 11 with direction, drive rope 7 and in elevating road 1, extend upward once more, its other end is connected with balance block 3.In addition, the 13rd, drive with traction wheel 11 and apply the tension force applicator of tension force by driving rope to the driving rope, in this example, balance block is installed at the front end of lever.In addition, provide tension force that the whole bag of tricks is arranged, do not limit in this example.20 are arranged on the machine mounting rail on elevating road 1 top, be positioned on the tectosome (not shown) of the tectosome (not shown) of the building that constitutes elevating road 1 or the elevator that guide rail (aftermentioned) waits, hoist cable be installed simultaneously with direction conversion belt pulley 8 or drive rope and drive with direction and change belt pulley 10.
Again, among Fig. 2, the 17th, brake equipment, the 18th, constitute brake equipment 17, with the slipper of hoist cable with direction conversion belt pulley 8 butts, the 19th, root a tree name hoist cable detects the speed detector of speed that this rotating speed promptly detects the cage 2 of lifting with the revolution of direction conversion belt pulley 8, and the 21st, hoist cable is fixed on adapter plate on the machine mounting rail 20 with direction conversion belt pulley 8.Described hoist cable with direction conversion belt pulley 8 be configured to stop when stopping and very much the time with hoist cable 6 between fully friction (for example so-called V groove, undercutting groove or full volume are constructed) takes place.
The following describes the lift appliance of the present invention of said structure.
The structure of this elevator is, by opening and closing the not shown door of taking advantage of mouthful and the door (not shown) of cage 2, allows the passenger enter in the cage, make then the cage lifting to the floor of fixed destination, the passenger is transported in a switching of carrying out.During cage 2 liftings, hang the balance block 3 that is held in hoist cable 6 other ends and also carry out reciprocal lifting simultaneously.During the elevator walking, hoist cable is untied slipper 18 with the brake equipment 17 on the direction conversion belt pulley 8 by being arranged on described hoist cable with direction conversion belt pulley 8 with described engaging of belt pulley 8 of direction conversion, can carry out the transmission of hoist cable 6.On the other hand, driving on the rope 7, driving with the lifting motor 4 (with reference to Fig. 7) on the traction wheel 10 at the driving rope, making described traction wheel 10 revolutions, and making balance block 3 liftings by transmitting driving rope 7 by not shown control setup drive installation.That is, pass to driving rope 7 by the rotary torque with described traction wheel 10, make balance block 3 liftings, the result is that the cage 2 that is positioned at hoist cable 6 other ends is carried out lifting.And, in case lifting motor 4 stops and cage 2 is stopped, then brake equipment 17 starts, hoist cable is fixing with direction conversion belt pulley 8, thus cage 2 is stopped and being kept.
In this lift appliance, for example,, be arranged on hoist cable with brake equipment 17 starts on the direction conversion belt pulley 8 even it is a certain unusual to have driven Suo Fasheng, also can keep cage reliably, so can reduce radical that drives rope or the specification of being convenient to relax rope.On the other hand, change when driving rope 7, with above-mentioned the same, cage 2 and balance block 3 are hung down by hoist cable with direction conversion belt pulley 8 by the hoist cable that is subjected to brake equipment 17 and prevents, so unnecessary cage 2 and balance block 3 are disposed especially can 7 taking-ups of driving rope.Like this, the replacing that drives rope 7 no longer needs special the fixing of cage and balance block handled, and can reduce the rope radical of changing object again, and flow chart is oversimplified, and compares with traditional elevator, also implements easily.
Again, in this lift appliance, because hoist cable 6 and driving rope 7 use respectively, the traction wheel 10 that particularly produces along with the acceleration and deceleration of elevator is partial to drive rope 7 one sides with the wearing and tearing of rope.Therefore do not exist and the engaging of traction wheel 10, hoist cable 6 when stopping very much, do not exist produce with hoist cable with engaging that direction conversion belt pulley 8 wears away, aspect the life-span, compare with traditional lift appliance, hoist cable 6 can increase the service life.Consequently the radical that the radical of hoist cable can be reduced to than the main rope 5 in traditional lift appliance by the specification that remodifies rope lacks.
On the other hand, by changing on the belt pulley 8 with direction speed detector 19 is set at hoist cable, can or drive speed detector 19 or the position detector that rope 7 is provided with cage independently with winch, need not consider to drive the slip of rope 7 and traction wheel etc., that is the action of, can obstructed overdrive system directly holding cage.Even particularly at the speed control system of management drive controlling or drive and to take place in the cable system when unusual, also can easily carry out and the independently speed of cage or the detection of position of drive system.Promptly, for example when cage is underload, in case because of driving control system or when driving unusual can not control of cable system, though because of the weight difference of cage and balance block quickens cage upward, but because the very shutdown feature (not shown) of cage is normally invalid to ascent direction, therefore balance block can not stop before at no show balance block side buffer (not shown), but in the present invention, because of the speed to cage directly detects, can directly cage be stopped, having the more device of high reliability so can provide.Promptly, in this example, have speed detector 19 and brake equipment 17 simultaneously owing to changing on the belt pulley 8 with direction at 1 hoist cable, mechanical aspects or electric aspect obtain cooperation (omitting diagram) easily, therefore can implement apace and the corresponding action of velocity anomaly, help the raising of lift appliance reliability.
Again, to drive rope 7 and separate with hoist cable 6, and can carry out the processing that stops of cage in hoist cable 6 sides, the result can alleviate the burden that drives the essential function in rope 7 specifications, be easy to change, so can be different with the main rope 5 in the traditional lift appliance for the specification of driving rope 7.That is, for example also can use and to drive rope 7 and change syntheticfibres rope making rope into, coat different shapes such as the V-type rope that forms flat flat pattern rope or flat pattern belts or form vee shape or V-shape belt with synthetic resin will be with the propulsive effort transmission aspect of traction wheel good 1 or many ropes from traditional steel rope.Again, can reduce to drive rope and drive with direction conversion belt pulley 10 or drive the diameter of rope, realize miniaturization, can easily be applicable to the material that obtains high friction between block sheave and the rope and surface treatment thereof etc. with direction conversion belt pulley 11.The result is as the elevator that does not need to be provided with in addition the Machine Room, is a kind of machines configurations design-calculated lift appliance that carries out easily for the elevator that all machines is accommodated in the elevating road.
In this example to will drive rope drive with traction wheel 10 be arranged on elevating road 1 top, will drive rope and change the structure that belt pulley 11 is arranged on the bottom of elevating road 1 with direction and be described, but be not limited to this, also can change for the bottom that the former is arranged on elevating road 1, with the top that the latter is arranged on elevating road 1, also can obtain same effect.Particularly traction wheel and winch are had sizable weight usually as one,, then also its weight can be utilized as the part of tension force applicator 13 if it is arranged on the elevating road bottom.
Again, this example is driving rope 7 to be connected the structure of carrying out lifting with balance block 3 be described, and carries out lifting but also driving rope 7 can be connected with cage 2, can obtain same effect, and this is self-evident.
Like this, by hoist cable and driving rope branch are arranged, brake equipment is set at hoist cable on direction conversion belt pulley, to drive rope is wound on the winch, can use material different and shape with conventional apparatus, the result can use the machine of miniaturization, can realize disposing easily the lift appliance of these machines.
Example 2
Fig. 3 and Fig. 4 represent embodiments of the invention 2, and Fig. 3 represents the concept map of the structure of lift appliance of the present invention, and Fig. 4 is that the hoist cable of Fig. 3 is with near the part figure the direction conversion belt pulley.
Embodiment 1 will drive the tractive that rope 7 is configured to so-called 1: 1, but this example is the structure by 2: 1 tractives, can reduce to drive with traction wheel 10 or drive load or the driving torque of rope with direction conversion belt pulley 11 etc. driving rope.Again, the function of tension force applicator 13 is also identical, but its structure has been done change.
In Fig. 3 and Fig. 4, except the part identical with formation illustrated in figures 1 and 2 indicates the prosign, the 16th, the guide rail of tension force applicator 13, the 22nd, carry the balance block on tension force applicator 13,23 are mounted in the cam on the tension force applicator 13, and the 24th, engage with cam 23, with respect to the position switch that detects its amount of movement with cam engagement to have or not that moves up and down of tension force applicator 13.Again, 25 are mounted in the upper direction inversion belt wheel on balance block 3 tops, 26 are mounted in the bottom direction inversion belt wheel of balance block 3 bottoms, and the 27th, with tension force applicator 13 and the fixed part binding of its guide rail 16 grades, the water bumper of supression tension force applicator 13 up-down vibration.
The following describes the lift appliance of the invention shown in the present embodiment of said structure.
Generally speaking identical with the invention shown in the aforesaid embodiment 1, its difference is: the tractive that drives rope 7 is 2: 1, on the tension force applicator 13 that drives rope 7, have along with the position switch 24 that moves up and down, again, drive the bottom that is arranged on elevating road 1 with direction traction wheel 10 with driving rope, will drive rope is arranged on elevating road 1 with direction conversion belt pulley 11 top.
In this routine lift appliance, driving rope 7 is that the fastening back of an end and for example machine mounting rail 20 (the belt pulley adapter plate 21 among Fig. 3) is descended, volume hangs on the upper direction inversion belt wheel 25 that is installed on balance block 3 tops, balance block is hung down the back rise, roll up the driving rope that hangs over elevating road top again and descend with back on the direction conversion belt pulley 11.Driving rope 7 after the decline hangs over the driving rope that is arranged at below the elevating road at volume and drives with rising once again after on the traction wheel 10, volume descends after hanging over the bottom direction inversion belt wheel 26 that is installed on the balance block bottom again, and is fastening in elevating road bottom and structure (not shown).
Again, in tension force applicator 13 of the present invention, except that balance block 22 with drive rope and drive, drive to form one and produce mass loading that the winch (not shown) of propulsive effort waits with described driving rope and will drive rope in driving rope and expand with traction wheel with the traction wheel 10.At this moment, tension force applicator 13 is guided by guide rail 16, and can move to the propagation direction that drives rope corresponding to the elongation that drives rope.Along with this moves, the engagement relationship that cam 23 and position switch 24 are installed changes, and can the mobile of tension force applicator 13 by the generations such as elongation that drive rope 7 be detected.
In this lift appliance, when cage 2 rises,, produced the bottom direction inversion belt of balance block 3 has been taken turns the effect that the driving rope 7 of 26 sides pulls down by driving revolution with traction wheel 10, balance block 3 descends, and the result rises the cage 2 by hoist cable 6 interlocks.That is, this is a kind ofly will drive the structure that rope 7 is adapted to so-called 2: 1 tractives, reduces by half owing to be applied to 1 load on the driving rope 7, and the driving torque of winch also reduces by half simultaneously, therefore compares the miniaturization that can realize winch with the occasion of 1: 1 tractive.
Again, owing to will drive the elongation of rope 7 or shrink moving as tension force applicator 13, can detect from the engagement relationship of cam 23 with position switch 24, therefore can be easily detect to any unusual generation or because of the extension that drives the ageing variation of rope etc., for example, can take in early days to shorten the measures such as operation that drive rope, can increase reliability as lift appliance.In addition, lifting because of cage 2, on tension force applicator 13, can produce vibration slightly when driving rope 7, might passenger's mood be impacted, but owing between tension force applicator 13 and guide rail 16, be provided as the liquid damper of vibration-stopping device, therefore can eliminate vibration, make passenger's mood stabilization.
On the other hand, for example when using synthetic fiber rope etc., extend though can strengthen with respect to the elongation of load and because of ageing variation, but owing to can carry out above-mentioned detection by the 24 pairs of elongations of position switch that are arranged on the tension force applicator 13, can easily take measures, and, though on the tension force applicator, also be easy to generate the vibration of rope elongation direction, can be, vibrate and restrain device inhibition vibration by the liquid damper 27 that is arranged on the tension force applicator 13.Like this, it is different with traditional main rope 5 or this routine hoist cable 5 to drive rope 7, drives rope 7 and can have the big selection of degree of freedom than above-mentioned rope.Because of using syntheticfibres, so do not exist and mutual the contacting of the metal of block sheave or belt pulley, so can realize noise little lift appliance takes place particularly.
Again, the operating state of the described position switch 24 of root a tree name promptly drives the degree of the elongation of rope 7, also can send the requirement of maintenance to maintenance department, perhaps easily stops the operation of elevator.
Thus, this driving rigging has and is suitable for than the big rope of the traditional elongation effect of synthetic fiber rope etc. for example.
Example 3
Fig. 5 and Fig. 6 represent embodiments of the invention 3, and Fig. 5 is the concept map of the structure of expression lift appliance of the present invention, and Fig. 6 is the vertical projection diagram of Fig. 5.
In Fig. 5 and Fig. 6, except that indicating the prosign to the identical part of formation shown in Figure 4 with Fig. 1,28 cage that are arranged on cage 2 bottoms are hung with direction and are changed belt pulley, and 29 balance blocks that are arranged on balance block top hang with direction changes belt pulley.
The following describes the lift appliance of inventing shown in the present embodiment of said structure.
Generally speaking identical with the invention shown in aforesaid embodiment 1 and 2, its difference is: cage 2 is provided with cage and hangs with direction conversion belt pulley 28, and balance block is provided with balance block and hangs with direction inversion belt wheel 29, and the tractive of hoist cable 6 is 2: 1.
In the lift appliance of this structure, because of being provided with the belt pulley 28 that cage is hung usefulness in cage 2 bottoms, so cage 2 can rise to the topmost of elevating road, can be with the actual required height minus of elevating road to Min..Again, hoist cable with brake equipment 17 is changed belt pulley 8 because of adopting the structure of 2: 1 tractives with direction, so not only the load from cage or balance block can be deducted half, and can further reduce the necessary braking force of described brake equipment, can further realize the miniaturization of brake equipment and hoist cable with direction conversion belt pulley 8.
The possibility of utilizing on the industry
The control device of elevator of the present invention is characterised in that hoist cable is separated with the driving rope, arranges in the hoist cable side Brake apparatus for example, even it is a certain unusual to have driven Suo Fasheng, is arranged on the brake apparatus 17 of hoist cable side Start also can keep cage reliably. On the other hand, change when driving rope 7, with above-mentioned the same, electricity Ladder railway carriage or compartment 2 and balance weight 3 are because being subjected to brake apparatus 17 controls, so needn't carry out cage 2 and balance weight 3 Special fixing just the disposal can easily be taken out driving rope 7. Like this, root a tree name hoist cable and drive separately institute of rope The characteristic that needs, the rope specification of applicable the best or rope radical.
Again, in will driving so-called 2: 1 structure of rope 7 formations, reduce by half owing to be applied to 1 load on the driving rope 7, the driving torque of winch also reduces by half simultaneously, therefore compares the miniaturization that can realize winch with the occasion of 1: 1 tractive.
And, can use the various structures different such as synthetic fiber rope, flat shape belt, flat shape rope, V belt or vee-belt or the member of shape owing to drive rope with traditional steel wire cable, therefore aspect the engaging of block sheave or belt pulley, can make the coefficient of friction optimization, suitable wearing and tearing less or low being used in combination of noise, and carrying out rope easily in elevating road sets up, realize the optimization of driving, help the save spaceization of elevating road.
Again, owing to changing on the belt pulley speed detector is set in the 1st direction with brake equipment, therefore can easily take the cooperation of mechanicalness or electric property, can implement apace and the corresponding measure of velocity anomaly, so help the raising of the reliability of lift appliance.
On the other hand, be provided with to driving the tension force applicator that rope applies tension force, therefore can under the situation of lax driving rope, set up, carry out reliably and driving engaging with traction wheel because driving is changed belt pulley with traction wheel or the 2nd direction.Because of being provided with the detector of tension force applicator amount of movement,, improving the unusual reliability of early detection rope or can implement to reduce the rationalization of the maintenance activity of rope etc. so can the extension that drive the ageing variation of rope etc. directly be detected again.
Again and since the tension force applicator be provided with restrain self vibration bumper to restrain the vibration that drives rope, therefore can restrain from driving the vibration that rope transmits to cage, help preventing the sense of discomfort of passenger's mood.
